To ((52 whomz't may concern. a

Be it known that L, ALFREDH. VVILLETT, a citizen of the United States, residing at West New Yor k,rin the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Fire- Brick Arches, of which the following is a specification. 7 V e This invention has reference toan improved form. of fire brick arch such as is used in fireboxes of locomotives, and 'to a novel construction of'fire brick for use in such structures,

7 arch which will be invertible and which will I rest securely upon the supporting tube either side up and have a suitable'bearing against" its oppositely disposed or complementary brick with intereng aging or interlocking means that will fit in either position.

: Another object of this invention .is the I provision of a brickof this invertible type which has a cut-away or recessed port-ion so disposed that when a number of them are assembled inv an arch and adj acent bricks placed in different positionsan aperture will be formed through the arch, while if placed in the's'ame position,.the arch will be closed or imperforate. 1 r j The above, as wellrassuch other objects as may hereinafter appear, I attain by means of a construction which I have illustrated in preferred form in the accompanying drawings, wherein Y s Figure 1 is a horizontal sectional view of a fire box showing the upper side of an" arch embodying my invention; Figure 2 is a longitudinal sectional view taken on the line II-II of Fig. 1; Figure 3 is a transverse sectional view through a fire box: Figure 4 is a section through one of the bricks showing the cut-away or recessed portion; and Figure 5 is an end view of one of themidand the size of the arch.

dlebric'ks usedin the archshown Figures 1'and8. p v V The fire box construction which I have illustrated comprises a fine sheet 1, a crown sheet 2, an inner back sheet 3, and a water leg 4, all of usual construction, andconnecting the water leg 4 with the water space 5 I provide two brick supporting circulation tubes 6 which, as'indicatedl in Fig.71,,are,

spaced a considerable distance apart, there being wing bricks 7 provided between the supporting tubes 6 and the side sheets 8 which wing'bricks maybe of'any preferred construction suitable to the requirements Referring now more particularly to 3, it will be seen that between the twoarch tubes 6, I arrange a series of pairs of bricks 9 whlchareprovided with'curved surfaces atlO resting against the tubes 6 formed so that they will provide a suitable support whichever faceof the bricks is placed upward. v

' The bricks 9 ar sloped 'upwardly, {150m the horizontal plane connecting thetubes 6 and rest against each other at'the center and each of the. bricks is providedwith' a pair of angular supporting faces/11 each' face having a projecting rib-12' and a come plementary recess 13, sh own most clearly in Fig. 5, these r bs or project ons and recesses being so disposed thattho'se on oneface are interengaged 'withf the companion fbrick' whichever face of thebrick 9; is placed uppermost. r I, Z Thesidesofthe bricks ,9have cut a'way provide: ap'erturesLthrough the arch if the bricks are. placed; with. each adjacent pair alternating in: position. as indicated in Figs parts or recesses 1a which extend more than half way through the thickness of thefbriick as a result of which the recesses 14" will bricks 9 are preferably made thicker through their upper endsthan at the end which rests upon the tubes as I secure thereby a broader contacting face 11 and greater strength for the central part of the arch.

I claim 1. A tube supported fire brick arch con-.-

struction comprising a series of pairs of invertible brickssupported between two/tubes, said bricks in each pair being" inclined toward and resting against each other and each": brick: having: at the meeting. end two oppositely inclined. supporting'surfaces constructed to permit the bricks to be rested against each other either face upward.

2. A fire brick arch structure comprising in combination a pair of brick'supporting' tubes and a series of pairs of bricks supported upon said tubes inclined toward and resting against each other with supporting faces constructed so that the bricksmay be rested against each other either face upward, and recesses insaid bricks so disposed as to provide; apertures through the arch when alternate" bricks are placed in inverted position and' to for-man imperforate' arch when the bricks are placed in the same p0"- s'ition. I

3. An invertible brick for fire box arch constructions inwhich' two bricks are adaptedflto lean against each. other inarche'd relatibn', having a support engaging surface at oneend andtwobrick engaging surfaces at the other end, one of which brick engaging surfacesis utilized in one position of the brick" and the other'in the other position, said support" engaging surface being adapted to cooperate with either of the two brick engaging. surfaces.

4. An invertible fire'brick for arch constructions adapted to lean against an adjacent brick in arched relation and having means at one en'd fo'r supporting it upon an arch: tube and provided at the other end with two oppositely inclined. faces so constructed. that the brickmay he leaned against anoth r brick either side up.

5. An invertible firei brick for arch constructions' adapted to lean against an adj acent brlckv and having means at one end for supporting it upon an arch tube and pro vided at the other end with two oppositely inclined faces sov constructed that it maybe leaned against another brick either side up, said faces having interlocking means for engaging acom'panion brick when in contact therewith V,

6. A fire brick for arch constructions adapted to. lean against an adjacent brick and having means for supporting it upon an arch tube and provided with. faces opposite its tube supported end so constructed that it may be placed either side up, said brick: having a recess formation: whereby when. a number are assembled to form an arch and alternate bricks are placed in inverted position, apertures will be formed through the arch but if all the bricks are placed inthe sameposition a closed arch will be formed.

7. An. invertible fire brick for arch constructionsadapted to lean against an adjacent brick and having means at one end for supporting itupon' an arch tube and provided at the other'end with two oppositely inclined faces so constructed that the brick may be leaned against another brick either side up, and tongue and. groove formations constructed to interengage with a companion brick'when placed in contact therewith.

8. A fire brick arch structure comprising in combination a series'of pairs of bricks the bricks in each pair beinginclined to ward and restingagainst each other with their inner ends constructed so that the bricks may be rested against. each other with either face upward, and. recesses in said bricks so disposed as to provide apertures through the arch when alternate bricks are placed in inverted'position. and to form an imperforate archwhen the bricks are placed in the samepo'sition'.

9. An invertible. brick for fire box arch constructions having a support engaging surface at one end; two brick. engaging sur faces at the other end, one of which brick engaging surfaces is utilized in. one position of the brick and the. other in the" other posie tion, said support engaging surface being adapted to cooperate with either of the two brick engaging surfaces; and a recess formation whereby, when a number ofsuch bricks are assembled to form an arch and alternate" bricks are placed" in inverted" position, apertures will be: formed through the arch, but whereby, if all of such bricks in an arch construction are placed in the same position, a closed arch willbe formed.

In testimony whereof, I have hereunto signed my name.
